What is a corneal ulcer?

A corneal ulcer is an open sore or epithelial defect with underlying inflammation on the cornea, the clear structure in the front of the eye. The cornea overlies the iris, which is the colored part of the eye and is separated from the iris by the aqueous fluid in the anterior chamber of the eye.

What does a corneal ulcer look like?

A corneal ulcer will often appear as a gray to white opaque or translucent area on the normally clear and transparent cornea. Some corneal ulcers may be too small to see without adequate magnification and illumination. See the first reference for pictures of a corneal ulcer.
